ABSTRACT:
An apparatus for fabricating absorbent, puffy sheet structure comprising a pair of plies of web material adhered in continuous linear regions interspersed with pocket portions. Portions of the plies forming the pocket portions include inwardly presented perforate bosses that enhance softness and water absorbency. The apparatus comprises a pair of matched-pattern, synchronously rotatable steel rolls each provided with small, sharp, ply-perforating members in the recesses between land areas, in combination with synchronous rotatable rubber embossing rolls urged against the rotatable steel rolls and intervening plies to form the perforate bosses.
